find the value of x in each
Answers
Answer:
Step-by-step explanation:
In first fig x=60deg as it is a isoceles triangle
Equal sides subtend equal angle..(i)
2nd fig
180-110=70linear pair
As it iscoceles
2a=110
X=55deg
3rd
As other one voa of 36
So by (i)
X=36
Answer:
The value of x in each:
(i) x= 50°
(ii) x=55°
(iii) x=36°
Step-by-step explanation:
(i) The given triangle is an isoceles triangle as two sides are marked to be equal, thus x=50° angle that the equal sides with make with the unequal side are equal.
(ii) The given triangle is isoceles, we know that sum of angles in straight line is equal to 180°, so the angle inside the traingle is (180-110)°=70°
The sum of all angles in a triangle is equal to 180°, so
(70+x+x)°=180°
(70+2x)°=180°
2x=110°
x=55°
(iii)The given triangle is isoceles, we know that opposite angles are equal, thus the angle on the inside of the triangle is equal to 36°
Since the triangle is isoceles, the angle formed between the equal and unequal sides are equal, thus x=36°
